Re: [CAD_CAM_EDM_DRO] Any "Best Practice" Recommendations for clearing chips ...

See the AutoEdit NC, post that I put up, it has feed and speeds, even if you
are on manual.

You can use WD-40 if you desire, but spray it into a bottle or something
first to get rid of the Propane propellant, and use a brush to apply the
WD-40. Or buy it in the non spray cans.
I often use Tap-Matic for Aluminum, and it takes very small amounts. I also
use the shop vac, when the chips are small and not long and stringy/springy.
